I am a 48-year-old male who lives in Tomball, Texas. My 15-year-old son and I climbed Kilimanjaro in late June. Despite ascending over 2000 meters (6600 feet) in the final 32 hours of our excursion, we never had serious symptoms of high altitude sickness. The most severe symptoms either of us had were mild headaches on a couple of occasions. Contrary to the experiences of others we encountered, we did not suffer from nausea, vomiting or delirium.

We also took moderate doses of Diamox on the last 3 days of the climb. I attribute much of our success to our decision to purchase and use for acclimatization to portable Altipower units. We each trained for five weeks, usually six days per week. I took this precaution because we live at sea-level and neither one of us had ever hiked in a mountainous area or climbed anything other than stairs. There is no reason for so many people to suffer while they climb (and I saw plenty of people suffering and one emergency rescue). One should enjoy, not merely endure, the summit experience.

I climbed Kilimanjaro last year and was only 1 of 7 in a team of 24 that made it to the top. I was the first woman along with two men from our team to get there first. I also did not suffer from altitude sickness thanks to the hypoxicator, it definitely made a tremendous difference. To be honest whether it’s for a trek or just to improve stamina and fitness this is worthwhile using.

Take care and best regards



I climbed Mt Kilimanjaro in Tanzania, East Africa August, 2003, and know the IHT played a big part in my success. I did not get high altitude sickness. My personal physician became interested in the machine and we determined a 10% increase in my hemoglobin. I trained on the IHT for 30 days.

Hi Oleg, just to say we have reached the top of Kilimanjaro thanks to the hypoxicator, it definitely made a tremendous difference, I was the only person to not suffer from altitude sickness at all! and I reached the top first by at least 20 mins in a blizzard!!

Thank you so much,

Best Wishes



Me and my husband just back from Tibet. Thank you for your Altipower which allowed us to pass a nice holiday in Lhasa without any particular problems.

I recently climbed Kilimanjaro. While climbing I met a fellow climber who had used your product. He seemed to have much more energy at higher altitudes than the others. I am interested in possibly purchasing your product for my own use.
